Be an eco-conscious beach bum this summer and take a sustainable holiday in South Beach, Miami at the Waldorf Towers. Located just a few steps away from the sea, the Waldorf Towers are one of the few LEED Gold accommodations in the area. The hotel will also soon be generating its own solar power, feeding any excess energy it makes into the local utility grid. Check out their cool retro-meets-modern interiors in our gallery above, and see even more pics of the stellar spaces over on their site!
